The operating basic principle of the 3-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the action of a pair of
synchronous gears, the two rotors rotate in reverse instructions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gas in the chamber is pushed to accomplish the
purpose of blowing.

Attribute of our roots blower:
one. Big adjustment of the air volume
two. Reduced Sounds
three. Large effectiveness
4. Reduced energy cosumption
5. Long time lifestyle
six. Reputable working, simple upkeep,small footprint

The Software of the Roots Blower

Routine maintenance and inspection
(one) Check all fasteners and locating pins conditions whether or not they are loosening.
(2) Usually check out regardless of whether the leakage phenomenon of the physique.
(3) Shell out focus to lubrication, sum of grease and noises when working,
decide no matter whether it functions under the required situations.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop position ≥
190ºC). Change the lubricant and grease right after initial 200 hrs managing, and exchange
once more after a moth working. Later, exchange the lubricant and grease in accordance to the
environment and lubricant (grease) top quality propose a appropriate EPT for a few
months.
(five) Constantly check out the inlet air filter, clean or replace the filter in time.
(6) Blower overload often not immediately displayed, so pay consideration to
the consumption and exhaust pressure, bearing temperature and the current enhance trends
of motor to determine whether or not the blower works typically
(seven) Just before disassembling the blower, the assembling relation and proportions
need to be recorded or calculated, make marks on components to make certain the authentic
requirements following assembling.
(8) When freshly machine or overhaul, the oil tank ought to be cleaned just before use
and suggest exchange all grease soon after 8 several hours operating.

Common failure reason and troubleshooting

No Failure Feasible causes Elimination approaches
one Friction
between the
impeller
(1) Impurities on the impeller,
ensuing in the hole is way too small
(two) Equipment dress in, resulting in a
large backlash
(3) The equipment is not nicely set,
can not sustain the impeller
synchronization
(four) Bearing wear resulting in
clearance increasing.
(1) Eliminate dust and verify
no matter whether there is damage elements
(2) Modify the gear gap, change
the gears if the gear backlash is
higher than the average thirty% to
fifty%
(3)Re-assemble the gears, maintain
the taper get in touch with location is to seventy five%
(4)Replace the bearing
2 Collision
amongst
impeller and
wall, the
impeller top
and casing
(1) Set up hole is not correct
(two) running force is as well
higher, exceeding the specified
benefit
(3) Operating temperature is as well substantial
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial area is not excellent
(one) Modify the gap
(2) Discover triggers of
overloading, reduced the strain
to the specified worth
(3) Verify the set up
accuracy and minimize the pipe
stress
(four) Examine and mend bearings,
and to make certain the clearance
(five)Relocation
3 Temperature
too high
(1) Oil in tank is as well much, too
thick or way too filthy
(two) Filter or silencer is blocked
(3)The stress is increased than
the specified benefit
(four)Extreme use of the
impeller, big gap
(five)Poor ventilation, indoor
temperature is high, ensuing in
inlet air's large temperature
(6) The rotating speed is also reduced,end result in the belt slipping.
(one)Reduce the oil amount or rely on
oil
(2)Remove of blocking objects
(3)Decreasing the stress via
the blower
(four)Restore its clearance
(five)Open up vents to lessen space
temperature
(six) Enhance speed to prevent the
belt slipping.
four Insufficient
movement
(1) The inlet filter is blocked
(2) Impeller use and the hole
will increase also much
(three) Belt slipping
(4) Massive imports strain loss
(5) Pipeline air flow leakage
(one) Thoroughly clean the filter dust and
obstruction
(two) Restore the gap
(three)Tighten the belt and improve
the variety of belts
(four)Adjust the inlet pressure to the
specified benefit
(5) Check and repair the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Higher tank place result in
leakage from the discharge port
(2) Seal wear, ensuing in shaft oil spills
(3) The stress is increased than
the specified price

 
(1)Lessen the oil level
(2)Exchange the seals
(3)Obvious the air vents, 2mm diameter faucet is mounted in the
middle chamber, open the faucet
beneath the wall
six Abnormal
vibration and
sounds
(one)Bearing clearance exceeds the
specified value or bearing use
(2) The equipment backlash is too
huge, not in a limited fastened
(three) The foreign objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation brought on the collision
brought on by overload,
(five) Friction among the impeller
and the inlet housing caused by
overheating
(6) Unbalance of the impeller
brought on by fouling or international
human body
(seven) Anchor bolts or other
fasteners are loosened
(1)Replace bearings or bearing
seat
(two)Reassemble equipment and make sure
backlash
(three)Cleaning blower, examine the
scenario is damaged
(4)Verify the back again pressure, check
the wheel and adjust hole
(5)Examine the filter and again
strain, improve the hole
amongst the impeller inlet and the
casing
(six)Clean the impeller and the
casing, to make sure that the impeller
clearance perform
(seven) Tighten the anchor bolts and
leveling the foundation.
seven Motor
overload
(1)In comparison with the required
stress, the force big difference
is big that the back again force or
the inlet stress is large
(two) In comparison with the
products demands, blower
circulation is also big, so its pressure
will increase
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating components
(5) The oil degree is too high
(6) Narrow V-belt is overheat,
vibration is also big, or pulley
is too modest
(1) Decrease the pressure to the
specified benefit
(2) Exhaust the excessive gas into
the ambiance or minimize the
blower speed
(3) Take away the obstructions
(4)Immediately shut down, verify
the explanation
(five) Change the oil to the proper
stage
(6) Check the belt stress, and
changed it with big diameter
pulley.
